CORRUGATING-MACHINE,

Specification of Letters Patent.

Patented Nov. 23, 1915.

, Application filed IDecember 11, 1914. Serial No. 876,603.

My invention is a machine designed to provide improved means for corrugating In the use of corrugating machines, the moisture of the paper and the tendency of the corrugations formed therein to expand frequently cause th product to stick to one of the rolls through which it is passed.

It is a primary object of my invention to provide a machine having eflicient means for preventing this sticking tendency by positively detaching the paper from the rolls as it passes therethrough.

The characteristic features of my improvements will more fully appear in the following description and the accompanying drawings.

In the accompanying drawings, Figure 1 is an end elevation of a machine embodying my invention; Fig. 2 is a rear elevation of the same; Fig. 3 is a sectional view taken on the line 33 of Fig. 2; Fig. 4 is. an enlarged sectional view taken transversely through one of the rolls in the plane of a circular channel thereof; Fig. 5 is a sectional view taken on the line 5-5 of Fig. 4:; and Fig. 6 is a sectional view taken-trans versely through the roll axes of a modified construction.

The machine illustrated in the drawings I comprises the housings 1 having the meshing corrugated rolls 2 journaled therein, the lower roll having a shaft 3 with a driving pulley 4 fixed thereon. These rolls are provided with the respective staggered circular channels 5 forming tracks or ways for guid:

ing corrugated planetary rings 6 of larger housing, said rolls being respectively prodiameter than the respective rolls and having planetary movements relative thereto, the rings having corrugations similar tothose of the rolls and being kept in proper registry therewith by reason of their mesh-. ing relations thereto. Bars 7 are carried by and are provided with. the

the housings1 gers 8 pro ect1ng toward the stationary bight of the rolls to supplement the action of the rlngs in detaching the paper 9 from the rolls as it is passed therethrough. As the sheet 9, is passed through the rolls 2, the

rings 6 coact with the rolls to form continuous corrugating ribs along the lines of contact, and, by reason of their greater diameters, provide means'beyond the bight of the intermeshing ribs for carrying the -corrugated material away from each of the rolls to which it might otherwise stick. The

fingers 8, which lap the rings on the oppositesides thereof, supplement this action. -The rolls are hollow and suitably heated by a flame formed by gas introduced through the pipe 12 and air introduced'through the pipe 11 by the pump 10.

Those skilled in the art will understand that'various modifications may be made in the machine without departing from the spirit of my invention. For illustration, in Fi 6, the rolls 2 are provided with plain di erential rings 13, of larger diameters than the respective rolls, which run in the channels 5 in lieu of the corrugated rings 6 for the purpose of detaching the corrugated section of the sheet 14 from the corrugations of the rolls 2.

Having described my invention, I claim: 1. In a corrugating machine, a corrugated roll and a ring of larger diameter than said roll, said ring being carried on said roll and revoluble therewith. 2. In a corrugatingmachine, a corrugated roll provided with a circular way and a corrugated ring oflarger diameter than said roll and controlled by said way.

3. In acorrugating machine, a pair of meshing corrugated rolls respectively provided with circular ways, in combination with similarly corrugated rings of larger diameter than said rolls respectively and controlled by said ways.

4. In a corrugating machine, a housing, meshing corrugated rolls iournaled in said vided with circular channels, and corrugated rings engaged in the channel or channels of the respective rolls, respectively meshing with the opposite roll and having planetary movements relative to the rolls on which they are mounted.

5. In a corrugating machine, intermeshing corrugated rolls, meens revolving With said rolls for detaching corrugated ma- In testimony whereof I have hereunto set 'my name this 10th day of December, 1914:,

in the presence of the subscribing witnesses.
